  Chromosome pairs
• What does DNA stand for?

  Deoxyribonucleic acid
• What are the sex chromosomes in humans?

  X and Y chromosomes
• How do the sex chromosomes differ between men and women?

  Women have two X chromosomes, while men have one X and one Y chromosome
• What is the structure of DNA?

  DNA is a polymer made up of two strands forming a double helix
• When do chromosomes appear in an X shape?

  Just before cell division during meiosis or mitosis
• If you unraveled all the DNA from a single cell, how long would it be?

  Over two meters long
• What is a gene?

  A small section of DNA that codes for a particular type of protein
• How is DNA organized within a cell?

  DNA is separated into 46 different sections called chromosomes
• What does a gene code for?

  A particular sequence of amino acids
• How many chromosomes does each human cell have?

  46 chromosomes
• How many different types of amino acids are there?

  20 different types
• Why can thousands of different proteins be formed?

  Because amino acids can be combined in many different combinations
• How many different types of chromosomes do humans have?

  23 different types
• How does DNA influence the type of cell produced?

  DNA determines which proteins the cell produces, influencing cell type
• What is the composition of the 23rd pair of chromosomes?

  The 23rd pair consists of sex chromosomes: one X and one Y chromosome in males, and two X chromosomes in females
• What protein do red blood cells need to transport oxygen?

  Hemoglobin

  The entire set of genetic material in an organism
• What determines whether a person is male or female based on chromosomes?

  Women have two X chromosomes, while men have one X and one Y chromosome
• How does an individual's genome compare to their parents' genomes?

  It is more similar to their parents' genomes
• When do chromosomes appear in an X shape?

  Chromosomes appear in an X shape just before cell division
• What is the significance of the complete human genome?

  It allows identification of genes linked to certain diseases
• What is a gene?

  A gene is a small section of DNA that codes for a particular type of protein
• What is an inherited disease?

  A disease caused by genes inherited from parents
• How can genes affect disease risk?

  Some genes may increase the risk of certain diseases
• How do genes relate to proteins?

  Genes provide the code for a specific sequence of amino acids that form a protein
• What can doctors do by looking at our genes?

  Choose more effective treatments for patients
• How many different types of amino acids are there?

  20 different types of amino acids
• How can genomes be used to trace human migrations?

  By analyzing small differences between populations
• Why can thousands of different proteins be made from amino acids?

  Because amino acids can be combined in many different combinations
• What do the small differences in genomes tell us about human history?

  When different populations separated
